Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20174, here are decompositions:

13 + 20161 = 20174
31 + 20143 = 20174
61 + 20113 = 20174
67 + 20107 = 20174
73 + 20101 = 20174
103 + 20071 = 20174
127 + 20047 = 20174
151 + 20023 = 20174

Showing the first eight; more decompositions exist.
